SMOKERS PETROL LIGHTER.

Application filed may 7, 1927, Serial No. 189,712, and in Great BritainMarch 2,1927.

This invention relates to smokers petrol lighters of the kind whereinthe wick tube is surrounded by a perforated, tubular shield which, whileadmitting air through its apertures to the flame, tends to prevent thelatter from being blown out by the wind, the shield being wide enough toadmit between it and the tube a closing cap which normally covers 4 thelatter. The object of the invention is to provide additional securityagainst the flame being blown out and also to render the flamesteadier,and the invention consists essentially in forming the shield withlouvred apertures 'as to effect a complete combustion of the carbonparticles, to deflect the wind from the wickand guard the flame againstbeing blown out. To enlarge the flame, moreover, and supply it withplenty of fuel, the wick tube is split longitudinally so as to partiallyexpose the sides of the wick as well as the top of the same.

The lighter is provided with a wick tube 0 which is split longitudinallyinto a plurality of claws between which the wick is exposed.-

Normally the wick tube is covered by a cap d g which is connected to apivoted arm 6 whereby it can be turned into and out "of operativeposition. The wick-tube, and also the cap cl, when the latter is inclosed position, are surrounded by a wind shield a provided with louvredair apertures b, the louvres being arranged so as to deflect the windfrom the source of the flame and guard the latter against being blownout.

In order to circulate the petrol vapours emanating from the exposedportions of the wick along the tube a and divert them towards I A strongand. steady flame is obtained in this adapted, while feeding air intothe flame so" the flame, the louvres are, according to the invention,arranged so as to causethe draught to sweep the whole interior of theshield. For this purpose the louvres are preferably directed towards thebottom of the shield so that the air current will pass across the wicktube in a downward sweep, as shown by arrows in Fig, 4, and carry thevapours towards the flame at the lee side of the shield.

manner. a

A good circulation of the vapours can also be effected by arranging thelouvres, as shown in Figs. 6 and 7, so that the draughtwill enter at atangent to the wick tube and sweep spirally-around the latter, asindicated by the arrows.

If a short wick tube is employed as shown in Fig. 8, the louvre platesmay be set in an upward direction.

The shape of the apertures may be varied. The elongated apertures shownin Fig. 1 may be replaced by a larger number of short apertures, asshownin Fig. 5.

The shield is normally covered by a plate f which is carried by the cap03 and which has an extension 9 covering the abrasive wheel h. 3
